fo all whom it may concern:

Be it known that I, ROCKY C. ,Ganonjvnnn a citizen of the United States, residing at Selmain the county of Dallas and State of Alabama, have invented a new and useful improvement in Apparatus for Treating Slag, (if which thefollowing is a specification.

This invention relates to a device for treating slag'for use in the manufacture or artificial blocks, or for other purposes for Which a granulated or. other slag may be There are many devices for treating or granulating slag which require the use of large quantities of Water, thus involving considerable additional expense in drying the slag in order to render it lit for 'use in connect-ion with cement, blocks, or for other purposes for which it is commonly used. There are other devices for treating the slag without adding Water, but the same are expensive in construction and being complicated are not always in condition tor use at the time the slag is tapped from the furnace.

The object of this invention is a' sim le will prepare the slagy or most of the purposes for which it is used at a minimum oi expense, and With the use of such a small amount .of Water that it is not necessary to go to the expense of subsequently drying out the slag.

' A brief description of. the process employed will make more clear the use of the mechanical construction employed by me and' which is the subject of this application.

As slag is tapped from the furnace it is run into a metal trough, and when the slag is to be used for brick, cement or otherpurposes Where a certain percentage of lime is required, accordin to the nature of the slag and the lime is added, in' a pulverized or hydrated form to said slag, the-latter being still in its liquid form. The 'slag is then run into a suitable reservoir Where any metal which may remain in the same is deposited and the` slag then `passes to a suitable trough from Wh1chit is run over' a curved longitudinal corrugated metal incline, theI curvature of the incline being gradually increased, so that as the slag gradually cools it Will continue said incline, and

Will then pass trom'the sameA through suitable discharge nozzles into a car, a suitable roller at the foot' of the incline keeping the slag broken to the required degree of line ness. In the accompanying drawings: Figure 1 is a perspective View of my apparatus, and Fig. Q is a longitudinal vertical section therethrough. g i

' In these drawings 1 represents a trouglhy into which the slagiis run after leaving reservoir above mentioned, Which reservoirv is not shown as it does not form a, part of this invention. This trough is provided with a vertically movable side 2 which carries rack bars 3, and a shaft 4 arranged parallel to said side' is provided with' gear Wheels 5 which mesh With vthe rack bars 3, and by turnin a handle 6 the'shat can be rotated throug the gears and rack bars, the side'2 being elevated, the bottom ci the desired width through which slag may pam. The slag passing from the' trough 1 passes on throng .an incline 7 corrugated to form a large number of gutters through which thesla-g travels, and from' these gutters, the slag falls upon a similarly l which the cool sla is discharged over* a roller 10, to a suita le car or wagon. The roller l0 may be driven in any ner and is provided with longitudinall tending bars 11 Which` strikeand bre slag as it I In orderrv that the slag maybe delivered to the car Without further breaking the roller 10 is mounted in slidable bearings 12 upon a frame 13 and can be readily moved backbe- 'exthe `neatli the incline and out of the' Way. A

pipe 14 is arranged transversely above the upper portion of the curved incline 8, said pipe being suitablyperforated` to discharge :i Water upon said incline, for the urpose of.

assisting in coolingl'the slag, an a supply pipe 15 leads to t epipe 14:. A p1 e 11ia also extends across the upper end ot t e ineline 8 and is suitably 'perforated and dispasses from the incline to the car.'

thus leaving an opening at i l desired manfoot of the incline is approached.

chargesV water into the grooves of the ineline, :for the' purpose of aiding in cooling the slag. f

.' .Any desired means can of course be employed for giving rotation to the 'roller 10.

In usin the apparatus above described any sultab e raking device, such as an ordi- 'nary rake may be employed for aiding movea downwardly extending gradually curved' incline, longitudinally fiuted, and means for discharging hot slag thereupon, the said 'inclinevhaving its curvature increased as the 3. A device for treating slag consisting of a gradually and increasingly -curved and longitudinally'uted incline, discharge nozzles carried by the foot of the incline, means for discharging hot slag upon the upper por-- tion of the incline, and a perforated Water 4. A device of the kind described comprising a trough, a movable sidefor said trough,

a short incline leading from said trough, a curved incline arranged in position to receive slag from the incline 'first.ment ioned, and means vfor discharging a small amount of Water upon the upper, portion of the curved incline.`

5. A device of the kind described comprising a trough, an incline leadingfrom said trough, the said incline being curved ,and being corrugated to form a plurality oiparallel longitudinal gutters, sleeves carried by the foot of the incline into which said gutters lead, said sleeves forming discharge noz- `zles, means for regulating the feed of slag from the trough to the'incline, and means for' discharging a small q uantityof Water I upon the upper ortion of the incline.
